The only issue I can see with Atlanta getting an expansion team (apart from the fact that it would be hilarious to see some people's heads absolutely explode) is that you'd need to add three more expansion teams along with them to keep things balanced.
Boston Bruins - Heritage
Given that some teams have a lot more history than others, those teams might get more than one Heritage set. This is the Bruins' Heritage Orr Edition. I'm retroactively renaming the previous one the Bourque Edition. Once again, this is from a pre-nameplate era so it doesn't have nameplates.
The sport as a whole is probably heading in that direction, especially since it's only a matter of time until the schools have to start paying players.
Florida Panthers - Alternate
This is simply an updated version of the alternates I did for the original version of the project. If it's not broken, don't fix it.
The more I look at these SS jerseys, the more I feel like all four of them missed the mark, but the Rangers' missed it by the smallest amount followed shortly thereafter by the Devils'.
